CAPPED PBQJ'ECTILE Specification of Letters Patent.

Patented April 20, 1909.

Application filed March 17, 1908. Serial Nude 1,628.

ful Improvements in Capped Projectiles; and

I do hereby declare the following to be a full, clear, and exactdescription of the invention,

such.as Willenable others skilled in the art to which it appertains tomake and use the same, reference being had to the acco'inpanyingdrawings, and to the figures of reference marked thereon, which form apart of this specification. I

. This invention comprises a cap to be placed on the pointed end of aprojectile, and also the particular method of applying the cap, wherebythe cap is insured against a'ccidental removal.

The invention comprises a projectile hav ing a pointed end and having anannular groove in the pointed end, the groove acting. to receive a splitring, and the split ringin turn having means cooperating with means onthe cap for adjusting the pressure .on the ring to force it in thegroove, and finally means [or permanently securing the adjustable meansin place.

The invention is further designed to apply the force to seat the ring inthe groove in a direction toward the point 01' the projectile, the pointacting to co-act with the seating force, and in this way there is noslack afterward, such as is present when the ring is forced in thegroove and not toward the point. When the old method is used there is achance for play when the seating pressure. is relaxed.

The invention is illustrated in the accompanying drawing, in whichFigure 1 is a section of a cap and a ring,

and the pointed end of a projectile is shown I broken away. Fig. 2 is aview of the cap and ring, and Fig. 3 is a small detail showinga modifiedform of construction.

Any style of projectile can be used that has a pointed end 10 which isprovided with an annulargroove ].l. A split ring 12 having a head 13 tofit in the groove is placed in the groove, the installation beingpermitted by reason of the splitting at 1 1. The split ring has on itsexterior a thread 15 which is preferably tapered, and it is embraced bya thread 16 on the annular flange 17 on the end of the cap 18. The cap18 is recessed to lit" the point 10, and when it is turned to screw thethreads together it bears on the point 10 and the pressure on'the ringis therefore toward the point. This pressure, with thecoinpressioncausedby the tapered screw, se-

curely seats the bead 13 of the ringsnugly in the groove of the shell,and there is no reaction of the'parts possible when rotation of the capceases. This is contrary to those constructions where the compression onthe binding element has been radial only or accompanied by .a pressureaway lI'OJIl the point. These old methods sometimes caused a slack whenthe pressure was relaxed at the completion of the operation, and anaccidental displace r-ent ol' the cap has happened.

To permit the screwing of the parts together I provide the ring 12 witha spanner hole or holes 19 and the cap with a spanner hole or holes 20.-\Vhen spanner wrenches are placed in these holes the parts can bescrewed orunscrewed. To lock the parts together, when all the parts areassembled, I place a tool in the hole 20 and mutilate or flatten thethread 15 of the ring so that the capfcannot be turned back to releasethe sp it ring.

An alternative construction is illustrated in Fig. 3, in which I employ.a split ring. 21 which is in turn inclosed by a solid ring 22 whichreceives the cap 18 as the ring 12. A beveled surface 23 throws thesplit ring 21 inward and toward the point when the cap is screwed home.

l do'not confine myself to a screw connection between the ring and cap,since other means may be employed forsecuring them together.

l-Iaving thus described my invention, what I claim is 1. The combinationof a shell having a pointed end and having an annular groove therein,with a split ring to be sprung in the groove, a cap bearing on thepointed end of the shell and on the ring, and an adjustable operativeconnection between the cap and the ring to compress the ring in thegroove.

2. The combination of a shell having a pointed end and having an annulargroove therein, with a split ring to be sprung-in the groove, a capbearing on the pointed end of the shell and on the ring, and anadjustable operative connection between the cap and the ring adapted tobe rotated to cause the compression of the ring in the groove.

-3.'The combination of a shell having a pointed end and having anannular groove therein, with a split ring to be sprung inthegroove, acap bearing on the omtedend'of the shell and on the ring, an anoperative connection between the ring and the cap adapted to draw thering toward the point of. the shell and compress it in the groove.

4. The combination of a shell having a pointed .end and having anannular groove therein, with a split ring inthe groove, a cap bearing onthe pointed end of the shell, and an operative connection between thecapand the ring to cause an adjustable pressure on" the ring, theoperative connection between the cap and the ring being adaptedto bedeformed to permanently secure the cap and the ring together. a r r 5.The comh'nation of a shell having a pointed end and having an annulargroove therein, with a split ring in the groove having a ta ered ortion,a cap bearing on the point of t e she and having avtapered portion toengage the tapered portionof the ring, and

' means for forcing the tapered portions together to compress the ringin the groove.

6. The combination'of a shell having a pointed end and having an annulargroove therein, with a split ring in the groove having a tapered ortion,a cap bearing on the point of the shell and having a tapered portion toengage the tapered ortion of the ring,- and means for forcing't etapered portions together to compress the ring in the groove and drawthe ring toward the point of the shell.

7. The combination of a shell having a pointed end and having an annulargroove therein, with a split ring in the groove having a screw-thread onits exterior, and a cap hearing on the pointed enxilof the shell andhaving a screw-thread to engage -the thread between the ring and-the canon the ring to lock the parts together, the.

threads on thering being adapted to be deformed to permanently securethem together.

8. The combination of a shell having a pointed end and having an annulargroove therein, with a split ring in the groove having a screw-thread onits exterior, a cap bearing on the ointed end of the shell and having ascrewt read to engage the thread on the ring to lock the parts together,and means for holding the rin against rotation, the cap having spannerho es for permitting its rota-'- tion, the spanner holes permitting theinset:

tion of atool for mutilating the thread onthe" ring.

9. The combination of a shell having a pointed'end, with a split ring,the pointed end of the shell and the split ring havingco' acting meansto 'prevent the Withdrawal of 'the split ring when the split ring iscompressed, a cap bearing on t e pointed end of the shell and onthering, andan adjustable o erative connection betweenthe cap and t e rinto compress the ring.

10. he combination of a shell having pointed end with a split ring, thesplit mug and thepointed end-of the shell having-coacting means forpreventing, the Withdrawal of the ring when the ring "1s com ressed, a

cap bearing on the pointed endo the shell and on the ring, and anoperative'connection compress the ring against the s ell and draw thering toward the point of the shll. V
